High level performance in world judo circuit: Notational analyzes of combat phase by weight categories

Abstract

This study analysed the time dedicated in the different phases of combat in all male weight divisions. For this, we analysed 548 combats. This time-motion analysis was performed through a previously-validated protocol. The main results indicated a significant effect for approach (p≤0.001), where the Half-Middleweight division showed a higher frequency vs. the others, except Half-heavyweight. For attack, Half-Lightweight showed a higher frequency versus Heavyweight (5.7±4.8 vs. 4.6±3.5 attempts; p=0.004). Extra-Lightweight showed a lower frequency of defences vs Half-Lightweight and Lightweight (2.2±2.6 vs. 3.8±3.2 vs. 4.4±3.7 attempts; (p≤0.047). Extra-Lightweight also showed a lower frequency of standing to ground transition vs. Half-Lightweight, Lightweight, and Half-Middleweight (p≤0.048). For groundwork, Middleweight showed a lower frequency of actions vs. the other divisions, except Heavyweight (p≤0.001). for the pause the Heavyweight division showed a lower frequency vs. Lightweight and Half-Middleweight (6.7±4.2 vs. 9.9±6.2 vs. 10.2±6.3 times; p≤0.019). In conclusion, our results can be applied to planning and prescribing specific training for the different weight divisions, taking into account the specific frequencies obtained in the combat phases. For lighter fighters, we recommend training focused on approach speed and gripping. For heavier weights, the training should be differentiated for muscle power development and groundwork combat.

Combat Time in International Male Judo Competitions: A Systematic Review and Meta-Analysis

“…The 8 studies that met the eligibility criteria in this systematic review were: Adam et al (2013) , Segedi et al (2014) , Boguszewski (2016) , Sterkowicz-Przybycien et al (2017) , Díaz-de-Durana et al (2018) , Barreto et al (2019) , Soriano et al (2019) , and Ceylan and Balci (2020) . Table 1 shows the qualitative analysis of these articles.…”

Judo performance: kinanthropometric importance for technical tactical and biomechanics

“…Investigations conducted weight division comparisons to provide further insights in the relationship between key-morphological variables and performance analysis 5 . When expensive high technology (ex.…”

“…Regarding the gripping phase, there is a range of primary and secondary factors influencing the development of judo expertise which need more research: gripping associated with high levels of power and produced torque appear to be one of the essential characteristics that determine success in competition 7 . Past study showed that middleweight athletes had higher gripping frequencies than other weight categories, particularly gripping more often with one hand targeting their opponent's back and sleeves 5 . Recent findings outline the relationship between balance control and the bilateral reactionary gripping task.…”

“…On the other hand, heavier athletes used more defensive grip configurations (i.e. back and collars) associated with the absolute weight on the opponent's shoulders, aiming to control their dynamic posture, and at the same time avoiding opponent's possible attempts to displace their balance (center of gravity), approaches and arm lever or minimal length techniques 5 .…”

Technical-Tactical Behaviors Analysis of Male and Female Judo Cadets’ Combats

“…Technical-tactical behavior analysis have been well-described in judo, verifying match demands (Coswig et al, 2018), techniques and muscle group specific torque production (Lech et al, 2015). Specifically, during female and male judo adult's competition, technical-tactical actions of different technical-tactical behaviors and pause strategies are highly varied and the associations between these variables together describe a judo's system of attack or fighting style (López Díaz- de-Durana et al, 2018). Despite this important finding about the senior age class, until now, it is not very clear whether there are technical-tactical behavior differences between female and male youngers.…”
